Abstract:
A solar cell is equipped with: a wafer; an n-type laminated body that is provided on the first main surface side of the wafer; and a p-type laminated body, which is provided on the first main surface side of the wafer such that the p-type laminated body is adjacent to the n-type laminated body in the X direction, and which extends in the Y direction. The wafer has: a lightly doped region that is doped to be n type; and a plurality of first main surface-side highly doped regions, which have an n-type dopant concentration that is higher than that of the lightly doped region, and which are provided between the lightly doped region and the p-type laminated body. The first main surface-side highly doped regions are discretely provided at intervals in the Y direction.
